Abstract:
Laboratory friction experiments are used on natural fault zone samples at cm/yr driving rates to demonstrate that there is abundant evidence of unstable slip behaviour which was not previously predicted, specifically for weak clay-rich fault samples. Samples are tested at 20°C and 10 MPa effective normal stress to approximate the in-situ condition, on powdered samples mixed with a 3.5% NaCl brine in a single-direct shear configuration.
